Outline of Final Research Achievements

The aim of this study is to develop anon-contact method for measuring the viscoelastic properties of articular cartilage by acoustic excitation at low frequency. In this method, the articular cartilage’s complex shear modulus is obtained by measuring the phase velocity of a stationary wave on the articular cartilage that is excited by a wide range speaker; the displacement response at the surface of the specimen is simultaneously measured at multiple points by two laser displacement sensors. The phase velocities of shear waves are obtained from the displacement responses and then the viscoelastic properties are evaluated using a Voigt model. The effectiveness of the system was investigated by measuring the viscoelastic properties of three gelatin phantoms with different collagen concentration of 2,5 and 8 wt. % at 50~120 Hz excitation.
